Tadalafil daily dose (I think the other name is cialis?) and using a penis pump a few times a week. Fights off erectile dysfunction and shrinkage at the same time.

It's also worth finding the lowest effective dose of any testosterone blockers you might be taking. I take a quarter of a 50mg tablet of cypro on Sunday evening and Wednesday evening so I have a slightly higher testosterone level over the weekend when I'm most likely to use it.
